    Legionella water testing is part of our large range of services that are designed to help our clients with Legionella prevention and management:

    Part of a Legionella risk assessment is testing for Legionella bacteria at different points wherever water is stored in your systems, testing water hygiene, and testing the water temperature. Legionella bacteria thrive in temperatures of 20-45 degrees Celsius, allowing them to multiply and spread rapidly.

    How We Test for Legionella in Your Water Systems

    When we do a full Legionella risk assessment, part of this is a physical inspection of your water systems. Each of our highly trained technicians is equipped with advanced technology to get the most scientifically accurate results.

    We complete Legionella testing in Hertfordshire on-site, on a monthly, quarterly, or six-monthly basis depending on need:

    1. We arrange a time convenient to you for a technician to carry out a full inspection on your premises. Each technician will test water temperatures with UKAS calibrated thermometer test kits.
    1. They will record the results of the inspections on our special online system ready for our office team to go through. 
    1. The specialist team will then provide a comprehensive review of these results and add comments and remedial recommendations.
    1. We then send you the detailed reports which include cost quotes for any recommended actions.

    Every report comes with explanations behind remedial actions and detailed guidance on how to carry them out. This bespoke service sets us apart from other Legionella service providers. We work with you every step of the way to help you achieve full Legionella compliance.

    Water Systems at High Risk

    Any water source that is capable of forming sediment, scale and any other type of bacteria provides a food source for Legionella bacteria to thrive. Combined with a temperature between 20-45c and any potential for aerosol release, many purpose-built water systems are at risk.

    The most common water systems that support the growth of Legionella are:

    • Spa pools
    • Hot tubs
    • Swimming pools
    • Dental apparatus
    • Showers
    • Healthcare Properties
    • Vehicle cleaning machines
    • Food manufacturing sites
    • Washing facilities
    • Industrial facilities like manufacturing sites

    These water systems and any others need a regular water risk assessment and regular Legionella testing to ensure health and safety standards are maintained.

    How Often You Should Get Legionella Testing?

    Your water system needs monthly checks and weekly flushing by an appropriately trained person. If you do not already have an in-house written control system, we recommend our monthly water testing and monitoring services.

    If you do have an in-house scheme in place and are sure that tests are being completed and recorded accurately, you should opt for our six-monthly checks. This ensures that testing is being carried out properly and in line with ACOP L8 and HSG274 regulations.
